To all whom t may concern.'

y Be it `known that I. JOSEPH W. GAMBLE, a

citizen ofthe United States,` residing at Carpentersville, in the county of Kane and State of lIllinois,` have invented new and useful Improvements in` vB:dance-Plates.: or sciL lat-ing lllembers,of which the following is a full, clear, concise, and` exact description, reference beinghad to the accompanying drawing, forming a part of this specification. My invention relates to improvements in dra-ft devices and has for its objectY the pro* duction of adeviee used in connection with tractors and plovvs in such a manner as to substantially eliminate side draft.

A further object is the production of a de vice by the use of which the plow will re main in line While traveling over the ground in raised position.

A further object of my device is the pro- `duction of a device of simple construction, cheaply manufactured, and not liable to breakage or disarrangement of parts.

These and such other objects as may hereinafter appear are attained by my device.I an embodiment of which is illustrated in the accompanying drawing, in which Figure .l represents a` plan view of fragmentary portions of a tractor and plow with my device in operative position therebetween. Fig. 2' represents a plan View of a modified torni of connection between the plow frame and draw liars.

Referringr now to the drawing.

l represents the rear ol? an ordinary hull tractor havingn r'levis 2 mounted on the frame in any :suitable manner, as for instance b v beiner bolted to rearwardly extend ing bars 3 and `l. An osoillatin Y member 5 is connected to thc tractor elevis oy means of a link (i. one end of' which is bolted lo the clevis n nd the other end to the member 5, at 8, the point of :xllmfhmcnt being intermediate the nppc-f' land .side corner 9 and the `furrow side of the plate.

The gang plow Il, the wheel 1'2 ol which travels in the, furrow, is provided with the usual plow clcvis 13 and an extension bar 14, extendingr in the saine direction as the clevis and continuing it substantially in front of the plow the width and beyond the ine of draft' of the ltractor over the edge of the line of the first furrow.

The land siclc draw bar 15 iS belted to the Application flied September 2. 1915.

outer end of the plow clevis at 16 and to th member 5 at 9. A furrow side draw bar 17 is pivotallxvvv connected to the extreme end of the extension bar 14 at 18 and at its for Ward end to the loiver furrow side corner of the balance plate at 19.

The line of the fnrroivs for a tivo bottom gang plow are indicated by lines 20 and marked furl-ow. lt will be seen that by this arrangement the heavier draf t is thrown on vthe furrow beam 21 oi the plow and the lighter dra ft on the land side beam 29.-. This is accomplished by the use of the member 5, the furrow side connection being snbstantially in the line of direct dra lit. and by this device and arrangement the plow is kept from swinging; to the left or into the land.

When the plow is aesineover rough ground. the side vibration will be solisten t-ially eliminated and in the event of the plow point striking an obstruction the balance plate will play sidevvise and the tend ency ot the end oi"- tlie beam to be thrown toward the land will be o come; the furrow draw bar being attached to the plate o on the furrow side Will into proper position as tion is passed.

A 'further advantage to be gained 'from the use of my device is that when the plow is raised it will remain in line. While traveling over the grenni'l and tlins be in position to drop inte operative position to do effective work at the proper time. This is a very i1nportant featnre it permita :more even and regalar g'ilowing and avoids continually readjnstinnjthe position of the plow each time zitter it has been raised from the le'ronnd.

l realize that my device is apparently i simple one` but the long;1 and hard usage to which l have pnt, it has 'folly demonstrated its eieetiveness and usefulness. .VVl1ile l have shown a triangular oscillatiii'g member. it. is evident that lv am not confined to that form or shape So long as' the points olf attachment ol' the draw liars and link are maintained in the position to pei-init the ell'ef-.tirfworking oi' the. device.

ln Fig. l have shown a modifi-cation in which the draw bars 23 and 24, which are connected lo the oscillating member 5, are connected lo a cross han" Q5. which in turn ic: connected to a pair oA links 26 by means bring 'the plate back soon as the obstruc` proper relative' lil-til all necessity for Eltlll i )l titl of bolts 27. These links 26 are connected by means of bolts 29 to the clevis 30, which is secured to the low frame 31 in such manner that the lin s 26 are substantiall in alinement with the beams 32 and 33 ot the plow frame.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with a tractor, a plow a low clevis, an extension on the furrow said of said clevis, a triangularly-shaped oscillating member pivotally connected on its shortest side and at a point intermediate thereof to said tractor, a furrow side draw bar connected at its forward end to the fur* row side of said oscillating member and at its rear end to the iclevis extension, a land side draw bar pivotally connected at its forward end to the land side of said oscillating member and at its rear end to the land side end of the plow clevis, and means for latermember and at its rear end to the furrow- Y side extension of the plow connection, said oscillating member being adapted to lie with: 35

one of its sides substantially in line with the furrow-side draft bar, a land-side draft bar pivotally connected at its forward end to the land-side corner of said triangular oscillating member and at its rear A end to the land,- side 'end of the low connection.

In Witness W ereof, I have hereunto subscribed my name. JOSEPH W. GAMBLE.
